·Field study was carried out to ~haracterize pnd to find out the growing degree unit (GDU)
harvest index (HI) and other morphological characters of recommended and .pipeline maize
. varieties Manakamana-2, Arun~4, Narayani, and Hill Pull White during winter 2000. Qu!Jiitative
.· characteristics viz.; .color of glumes, anthers and silk wer.e distinctly different among vqrieties as
coi?'tpared to quantitative characteristics but there was no, variation for the color of ~tem, leaf
and central vein. Manakamana-2 and Hill Pull White had pure white coloured co,bs while :Arun-4
and Narayarli had white and pink/red coloured cobs. Hill Pull White had white dent seed-type
and others were yellow flints. Arun-4 required less GDU for 50% Tasseling (588.9), 50% silking
(624.9) and physiological maturity (1312) while Hill Pull White required maxi'!'"m GDU i:e.
797. 8, 828.5 and 1704 for 50% Tasseling, 50% silking and physiological maturity respectively.
~ Manakamana-2·attained maximum leaf area index (LAI) 1.9936 followed by Ntirdyani (1.9627) .
and Hill Pull White (1.8943) at silldng stage. Narayani Producecf.the highest harvest index (HI)
0.38 followed by Aru_n-4 (0.36) and Manakamana-2. (0.34). Narayani had the highest shelling
per cent (82%) followed by Hill Pull White (79%) and Arun-4 (78%) respectively among the
tested varieties.
